Reports & Analytics is the only tool that supports rollup reports, and Adobe no longer recommends using rollups. See “Report suite approaches” for alternatives.
To create a rollup report suite:
Click Analytics > Admin > Report Suites.
In Report Suite Groups, click Add next to the Rollups heading.
In the Create a New Rollup dialog box, provide the following information:
Report Suite ID: The rollup’s report suite ID.
Report Suite Title: The report suite title that appears in the Site menu.
Time Zone: The time zone where data is reported.
Click Create Rollup.
